Launched in 1976, the “Nautilus”, named after Captain Nemo’s submarine (created by Jules Verne in his “Vingt mille lieues sous les mers”), was an immense breakthrough from Patek Philippe’s conservative designs and proof that Haute Horlogerie and audacity can go hand in hand to create an icon that is still relevant 40 years later.

Legend has it that the idea of creating a watch in the shape of a porthole found on transatlantic liners came to designer Gérald Genta (1931-2011), a Genevan designer jeweller, whilst dining at a restaurant during the Basel fair and looking at the Patek Philippe team dining on a table opposite his. The whole design having taken no more than 5 minutes!

Patek Philippe produced two versions of the Nautilus Ref. 3700 in steel:

· 3700 / 1, from 1976 to about 1981, that featured a straight bracelet and reference;

· 3700 / 11, which was in production from 1981 to 1990 has a tapered steel bracelet.

Beating within is the Cal. 28-255 C (based on the legendary Jaeger-LeCoultre JLC 920 self-winding movement; which was never used by Jaeger-LeCoultre!) and heavily modified by Patek Philippe, it was at the time the world’s thinnest self-winding movement with date (3.05 mm. thick) and found in two other models representing Haute Horlogerie groovy chic: Audemars Piguet’s “Royal Oak” and Vacheron Constantin’s “222”; the first, also design by Genta; the second, designed by Jorg Hysek, a young German designer (born in 1953).

Originally, the Ref. 3700 / 1 A comes with a coveted cork presentation box.

Owing to a thinner calibre, the 3700 / 1 A retains a slimmer profile than its 21st century descendent, the 5711 / 1 A, introduced on the 40th anniversary of the 3700 in 2006.

The “Jumbo” moniker refers to the 42 mm. case, with wide flat bezel, integrated steel link bracelet, and self-winding movement, possessing a rather masculine aesthetic compared to the smaller dressy gold mechanical watches of the time.
